largefiles: properly pass kwargs into url.open

The url.open function has acquired a lot of kwargs over the years.
When running `hg import http://example.com/hg/diff/1`, since at least
a708e1e4d7a8 in March, 2018, the calling sites for url.open try to
pass a `sendaccept` parameter that largefiles' override doesn't accept.

Currently that stack traces something like this:

  Traceback (most recent call last):

      return url.open(ui, path, sendaccept=sendaccept)
  TypeError: openlargefile() got an unexpected keyword argument 'sendaccept'

So, just accept and pass along any kwargs of the overridden function.
